Plants grown on sandy soil, are grouped under

Options

A. Lithophytes
B. Psammophytes
C. Hydrophytes
D. Xerophytes

Answer

To determine the correct classification of plants that grow on sandy soil, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of Plants**: Begin by identifying the different categories of plants based on their habitat and adaptations. The question provides four options: lithophytes, samophytes, hydrophytes, and xerophytes.

2. **Evaluate Lithophytes**:
- Lithophytes are plants that grow on rocks and stones, specifically in crevices.
- Since sandy soil is not a rocky environment, this option is not applicable.

3. **Evaluate Samophytes**:
- Samophytes are plants that thrive in shifting sands, which are commonly found in desert regions.
- These plants have adaptations that allow them to survive in unstable sandy conditions, making this option a strong candidate.

4. **Evaluate Hydrophytes**:
- Hydrophytes are aquatic plants that grow in water and require a high amount of moisture.
- Since sandy soil does not provide a water-rich environment, this option is not applicable.

5. **Evaluate Xerophytes**:
- Xerophytes are plants adapted to survive in dry and arid conditions, such as deserts.
- While they can tolerate low moisture, they are not specifically adapted to sandy soil environments.

6. **Conclusion**: Based on the evaluations, the correct classification for plants that grow on sandy soil is **samophytes** (Option B), as they are specifically adapted to thrive in shifting sands.

### Final Answer:
Plants grown on sandy soil are grouped under **samophytes**.
